Spontaneous Formation and Electrogenerated Chemiluminescence of Tris(bipyridine) Ru(II) Derivative Nanobelts

Abstract

The single crystalline nanobelts were successfully fabricated with an ionic compound by a simple reprecipitation method. The compound used is the water-insoluble derivative of tris(bipyridine) Ru(II), [Ru(bpy)2(4,4'-(CH3(CH2)14COO)2-bpy)](ClO4)2. The prepared nanobelts show an enhanced fluorescence emission and relatively strong electrogenerated chemiluminescence (ECL), that have potential analytical applications. More interesting, ECL of a single nanobelt deposited on an ultramicroelectrode was observed. The observation of ECL in such nanostructures leads to the development of a new class of ECL systems that may prove useful for a variety of purposes.

Applications of Nanomaterials in Electrogenerated Chemiluminescence Biosensors

“…While most research has focused on inorganic compounds, polymers, or low-molecular weight organic compounds, Recently, a study has been performed on ionic compounds such as [Ru(bpy) 2 (4,4′-(CH 3 (CH 2 ) 14 COO) 2 -bpy)](ClO 4 ) 2 , the water-insoluble derivative of tris(bipyridine) Ru(II)[106]. The Bard group fabricated nanoscale nanobelts from such an ionic compound by using a simple reprecipitation method.…”

Barrier-oxide layer engineering of TiO2 nanotube arrays to get single- and multi-stage Y-branched nanotubes: Effect of voltage ramping and electrolyte conductivity

“…Recently, one-dimensional (1D) nanostructures, such as nanotubes [1,2], nanorods [3], nanowires [4], and nanofibers [5], have been widely studied because of their characteristic geometrical morphologies, unique physical and chemical properties, and potential applications in optical and electrical devices [6]. TiO 2 nanotube arrays (TNAs) formed by self-ordering anodization have attracted wide interest in science and technology due to the high number of potential applications aided by the tubes ionic, electronic and biomedical properties [7][8][9].…”

Photocatalytic Reduction of Nitrobenzene by Titanium Dioxide Powder

“…Since that time, semiconductor photocatalysis has been investigated extensively by scholars in many fields. [2][3][4][5][6] It is known that semiconductor containing band structure is usually constituted by a low-energy electron valence band (VB) and an empty high-energy conduction band (CB). Valence band (VB) and conduction band (CB) are separated by the forbidden band.…”
